A fuel injection amount in an engine is determined based on a cylinder air volume equivalent fuel injection amount and a wall flow correction amount. The fuel injection amount is also decreased in an initial injection when fuel injection is restarted after it is has been stopped. In this way, sudden torque increases are suppressed without causing a loss of engine rotation speed when fuel injection is restarted after it has been stopped.
